loosely white-tomentose, not glandular.

(sometimes lignescent near bases) proximally glabrescent, distally persistently tomentose, at least in the region of the heads, not glandular.

blades (crowded, internodes 1–5, sometimes to 10 mm) narrowly obovate to subspatulate, 1–3(–6) cm × 2–8 mm (distal smaller, oblanceolate to narrowly oblong or linear), bases subclasping, usually decurrent 1–2 mm, margins weakly revolute, faces mostly concolor to weakly bicolor, abaxial gray-tomentose, adaxial usually gray-tomentose, sometimes glabrescent, neither glandular.

blades (not crowded, internodes mostly 5+ mm), oblong-oblanceolate to oblanceolate (the distal lanceolate), 1.5–5(–8) cm × 4–10(–15) mm, bases auriculate-clasping, not decurrent, margins flat or slightly revolute, often undulate, faces bicolor (at least basal and proximal cauline), abaxial white-tomentose, adaxial bright green and ± densely glandular.
